Need some opinions and pros/cons for the decision on purchasing a 6x12 vs 7x12 BriMar dump. Both would be the 10K since I am pulling with a 2500HD. Weight for the 6x12 is 2680lbs. and the 7x12 in 2815lbs. The reason for staying at 12ft long in too keep the weight and overall length down. Any ideas..........
